Can You Spell Banjo without the "O"?

Interesting.
I just received these brake lines from Galfer. Decent looking stuff. Lightly coated with clear plastic. The price seemed better that Goodyear and I heard they do color coatings so I gave them a shot. It turns out colors are only avalilable only on motorcycle hoses.

Anyway the thing is, these are for Shimano calipers and my orig hose has a recess/groove near the ID of the banjo for a tiny O-ring seal. This doesn't. It does come with metal washers but I wonder if this will work?
